  1. I've now removed the 10mm spacer so the distance from the reducer to the front of the Lodestar is now 53mm - this gives a focal reduction of about F3.5 and much lower distortion.

     

    I will continue to experiment with the spacing but am happy with the results:

  2. Hi

    You do not need the flip mirror - it just makes getting a target on the screen easier and you can flip between visual and video.

    The length of the T extension between the flip mirror and the fine focuser will vary depending upon whether or not you have a focal reducer fitted to the nosepiece of the camera (shorter with no reducer).
